Your STC rebate checklist should cover the system’s eligibility, panel and inverter details, installation postcode, deeming period and the installer’s accreditation under the current scheme rules. Confirm the quote clearly states whether the STC value is being assigned to the installer as an upfront discount, and ask what documents you will receive, such as invoices, product information and installation records. Check that the installer will complete the required declarations and submit the certificates correctly. The final value and eligibility depend on the rules in force and your circumstances, so verify details with your installer and the Clean Energy Regulator.
